Letters Patent'Nc. 111,594,"dated- February 7, 1871A IMPROVEMENT IN FEED-CUATTERS.

The Schedule referred to in these Letters Patent and making part of the Ilmo.

I, Joux L. Wnrrrmn'nau, of Ghicopee Falls, in-

the eouulj of Hampden, (Qommonwealth of Massachusetts, have invented eci-rain improvements in Feed-Cutters, ofwhieh the following is a specification.

Nalin-c and Object 0j' the Int-ration.

My invention relates to thc Combination, with the .feed-rollers and their adjustable gearing, the knife- .plate and its-bed, and with the knife-arbor, of the iron side frames, each being east in one piece with slot for reception of'end of ledger blade-bed, and bearings to receive adjusting screws and shafts of feeding-rollers and knife-arbor, so that one size of eastinfjr will do for any-size machine.

Description of Accompanying Drawing.

Figure I isa plan view of a machine embodying my invention; j

Figure [I, an end view of the feed-rollers with Jthe varia-ble gearing; and v 1 Figure III is'a side view of one of my side frames cast in one piece.

4 General `l)cscrpl ion.

The hay, straw, or whatever it may be desired to ent, is passed through the rollers A B. 'lho upper one, A, beingl corrugated or provided with projections upon its surface, it is evident the speed with which the substance to be cut is supplied to the. knives depends upon the'rapidity with nvhich the roller A revolves, the lower roller acting only as a revolving4 surface to prevent friction, andthe faster the straw is pushed by the action of roller, the further it will be carried past the cutting-edge of the knife-plate O in the interval of one knife passing it until another comes around, and, consequently, the longer.l

The ends of the knife-plate bed are let into slots D' in the side frames E E, and are adjusted by setscrews o working in the frame laterally, and screws b b' vertically, so that they can be moved to arequired distance from the knives and secured in 'that position. I cast my side frames E E of one piece, with the necessary slot, screw-holes, and bearings for shafts,

which is a great advantage, as the frames can by this means be much more substantially constructed to resist the vibration of the operating parts, the machine can be more compact] y made, and the same side frames will do for any-size machine, as the size depends. upon the length of the knives and feeding-rolls.

Claim.

The arrangement of the iron side frames or journals E li, cast in one piece and having journals for the rollers A B and shaft carrying the cutting-knives, and slots l) D for the reception of the end of the bed-plate (l, with screw-holes for the adjusting screws a a and b I) that regulate the same, substantially as shown and described.
